49863 nj2013_usace_ncmp_newjersey_m4927_metadata Data Set Published / External 49401 Lidar - partner (no harvest) Project Completed 2015-08-13 These files contain classified topo/bathy lidar data. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (valid bathymetric data). Classes 1 and 2 are defined in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. These data were collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system. CZMIL integrates a lidar sensor with simultaneous topographic and bathymetric capabilities, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. Native lidar data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 National Adjustment of 2011 (NAD83 NA2011). Vertical positions are referenced to the NAD83 NA11 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID12A model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88) and OCM transforms the heights back to ellipsoid for data storage. DEMs products have not been reviewed by the NOAA Office for Coastal Management (OCM) and any conclusions drawn from the analysis of this information are not the responsibility of NOAA or OCM. The data are available upon request via email at: coastal.info@noaa.gov. Please provide the name of the data set and "DEM Request" in the subject line. These data were collected as a part of the NCMP to depict the elevations above and below the water in the New Jersey coastal zone. 10507 A footprint of this data set may be viewed in Google Earth at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/4927/supplemental/nj2013_usace_ncmp_newjersey_m4927.kmz Theme Global Change Master Directory (GCMD) Data Center Keywords DOD/USARMY/USACE/SAM/MOBILE/OPJ/JALBTCX > Joint Airborne Lidar Bathymetry Technical Center of Expertise, Mobile District, South Atlantic Division, U.S. Army Corps of Engineers, U.S. Army, U.S. Department of Defense Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > HUMAN DIMENSIONS > ENVIRONMENTAL GOVERNANCE/MANAGEMENT > LAND MANAGEMENT > LAND USE CLASSES Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL LANDFORMS Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL PROCESSES Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > BATHYMETRY Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > SEAFLOOR TOPOGRAPHY Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION Theme ISO 19115 Topic Category elevation Spatial Global Change Master Directory (GCMD) Location Keywords VERTICAL LOCATION > LAND SURFACE Theme GCMD Data Center themekeys v7 Joint Airborne Lidar Bathymetry Technical Center of Expertise Theme GCMD Data Center themekeys v7 Mobile District Theme GCMD Data Center themekeys v7 Spatial Data Branch Theme GCMD Data Center themekeys v7 United States Army Theme GCMD Data Center themekeys v7 United States Army Corps of Engineers Theme DOD/USARMY/USACE/SAM/MOBILE/OPJ/JALBTCX > Department of Defense Theme IWG-OCM Theme National Coastal Mapping Program (NCMP) Theme New Jersey Theme SOLID EARTH > GEOMORPHOLOGY > COASTAL LANDFORMS/PROCESSES Theme Spatial Data Branch Theme U.S. Army Corps of Engineers (USACE) Theme United States Theme United States Army Theme United States Army Corps of Engineers Theme VERTICAL LOCATION > LAND SURFACE Theme VERTICAL LOCATION > SEA FLOOR Theme imageryBaseMapsEarthCover Theme location Theme oceans Temporal 2013 Temporal June Office for Coastal Management Charleston SC Data Set As Needed las LiDAR points in LAZ format (Classes 1,2,29) none Any conclusions drawn from the analysis of this information are not the responsibility of USACE, JALBTCX, NOAA, the Office for Coastal Management or its partners.

This data set covers the spatial extent of topographic lidar data obtained during this survey. During inspection and QC of the lidar point cloud, flightline to flightline elevation differences met the CZMIL sensor specifications. 1 These data were collected using the CZMIL system. It is owned and operated by the U.S. Army Corps of Engineers (USACE). The system collects topobathy lidar data at 10 kHz and RGB imagery at 2 Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V 510 equipment. All raw data streams are transferred to the office for downloading and processing in CZMIL's Hydro Fusion software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. PFM_ABE software then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID12A model and exports valid lidar data as a series of unclassified LAS files. 2013-06-23T00:00:00 2 LAS files are imported into GeoCue V2012.1.27.7, which is a geospatial workflow production and management software tool employed by JALBTCX to perform and monitor production of data products. Upon import into GeoCue, a customized classification macro, built upon the TerraScan V13 module within Microstation V8i, classifies valid topobathy data as ground points (2) and unclassified points (1), and valid bathymetric points (29). Upon completion the macro, the classification results undergo quality control and any misclassified points are manually edited. In areas of dense vegetation the bare earth ground points might be incorrectly classified due to the inability of the laser to penetrate the canopy and reach the bare ground. In these areas, JALBTCX defaults to the algorithm's "ground" surface instead of manually reclassifying those points. They are partitioned into a series of 5km or quarter quad delivery boxes, one Classified LAS file per box. The format of the file is LAS version 1.2. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (valid bathymetric data). 2014-07-23T00:00:00 3 The NOAA Office for Coastal Management (OCM) received the topographic/bathymetric files in LAS format from USACE. The files contained lidar easting, northing, elevation, intensity, return number, etc. The data was received in Geographic Coordinates (decimal degrees) with vertical heights referenced to ellipsoidal Geoid12a values (meters). The LAS files were converted to LAZ compressed format for data storage and Digital Coast provisioning. 2015-07-22T00:00:00 gov.noaa.nmfs.inport:49863 Anne Ball 2017-11-15T15:22:49 SysAdmin InPortAdmin 2022-08-09T17:11:38 2022-03-16 OCM Partners OCMP 1002 Public No No 2022-03-16 1 Year 2023-03-16
